COTTON-GIN.

SPECIFICATION forming part of Letters Patent No. 328 .067, dated October13, 1885.

Application filed July 23, 1885. Serial No. 172,481. (No model.)

To all whom it may concern: Be it known that I, GEORGE L. RoLLINs, acitizen of the United States, residing at Bridgewater, in the county ofPlymouth and State of Massachusetts, have invented a new and usefulImprovementin Gotton-Gins, of which the following is a specification.

In cotton-gins now in general use, and particularly such as described inthe patent of J.

N. Wilson and G. W. Payne, N 0. 20,120, April 27, 1858, the hullerrolleris driven by means of a belt, and whenever it becomes necessary to raisethe breast the belt is thrown off the sheaves, and thus becomes liableto be caught in thesaws. When cog-wheels are used, they become cloggedwith the cotton.

It is the object of myinvention to dispense with belts and cog-wheels,and thereby obviate the objections incident to their use.

In an application filed April 9, 1885, N 0. 161,178, I have shown anddescribed a. friction-Wheel mounted in a weighted and adjustable leverand arranged to bear upon the upper portions of thesheaves on the shaftsof the saw-cylinder and huller-roller, the lever being attached at oneend to a slotted adjustable plate secured to the frame of the machine.

My present invention, though involving a similar principle, isdifferently constructed; and it consists of a friction-roller connectedto one end of aweighted and slotted lever, the slotted portion of thelever being supported upon a pin or bolt secured to an adjustable plateor clamp bolted to a portion of the frame of the machine, thefriction-wheel being made to bear against the lower portions of thesawcylinder sheave and on the side of the hullerroller sheave.

Referring to the accompanying drawings, Figurel is a side elevation andpartial section of a cotton'gin embodying my invention. Fig. 2 is a topview of the same, and Fig. 8 is a view in detail of the adjustable platethat carries the lever. r

- A A represent a portion of the frame of a cotton-gin. B'is thesaw-cylinder shaft, and O the sheave on the same. D is the hullerrollershaft, and E the sheave on the same. All these are parts of machines incommon use.

K is a slotted plate secured, by means of a bolt and nut, Z, to theframe A, so as to be adjustable higher or lower on the frame, as may berequired. To the plate K is attached a bearing for a pin or bolt, L,which passes through the slot 9 in the lever G, and which constitutesthe fulcrum of said lever. At the outer end of the lever is anadjustable weight, I, and on the inner end of said lever is journaled afriction-wheel, H, which bears against the sheaves O and E on the shaftsof the sawcylinder and huller-roller, respectively.

By the use of the slotted lever, as shown, I

am able to dispense with the spring, as shown and described in thepending application above referred to, and the friction wheel H willadapt itself to the sheaves O and E under all circumstances.

What I claim as my invention, and desire to secure by Letters Patent, is

In a cotton-gin, the combination, with the sheaves of a saw-cylindershaft and a hullerroller shaft, of a friction-wheel, H, a weighted andslotted lever, G, an adjustable plate, K, and the frame A, as and forthe purpose set forth.

' In testimony whereof I have signed my name to this specification inthe presence of two subscribing witnesses.
